Definitions

  • the invention relates to a sealing device for lateral sealing at least one overpressure or adjacent to a moving surface Vacuum zone in a paper machine with at least one at least movable in areas in a receiving area of a holder Arranged sealing element that with to apply to the moving surface a contact pressure can be applied.
  • the invention enables the contact pressure with which the Sealing element is applied during operation, i.e. at the moving one Surface applied sealing element, to maintain and thus for to provide a resilient mounting of the sealing element. In this way vibrations of the moving surface can be absorbed, which at relative to the immovable sealing element for increased wear of the sealing element would lead.
  • the stop element 70 engages behind a radially inner boundary surface the undercut with respect to the radial direction representing groove 16, this boundary surface as a radially inner, stop surface 16a interacting with the stop element 70 serves.
  • the facing the jacket 20, in the state according to the figure boundary surface of the groove 16 spaced from the engagement section 75 forms a radially outer stop surface 16b of the sealing element 15 for the stop element 70.
  • the return element 35 could - for example, with a correspondingly modified arrangement be designed as a tension spring.
  • the contact pressure hose 55 pressurized. That then relative to the Holder 10 on the jacket 20 to move sealing element 15 takes with its radially inner stop surface 16a on the stop element 70 the engagement portion 75 against the restoring force of the return element 35 with.
  • the from the clamping member 30, d. H. from the pressure hose 50 over the Piston 60 clamping force exerted on stop element 70 is such dimensioned that the sealing element 15 even with an increase in the the contact pressure applied 55 no more pressure the jacket 20 can be moved.
  • the fluid pressure within the pressure hose 55 can then to the clamping fixation of the stop element 70 also by one certain amount be reduced in such a way that still ensures is that the sealing element 15 without play between the pressure hose 55 and the stop element 70 is held to its sealing function to fulfill.
  • the sealing element 15 is in any case due to the pressure standing pressure hose 55 resiliently mounted. Movements that are transferred to the sealing element 15 via the jacket 20 thus caught by the sealing device according to the invention, whereby the wear of the sealing element 15, d. H. the wear of the Wear layer 15a is minimized.
